Beit -known that LIGNAE MARTIN, of Newark, Essex county, New Jersey, have invented a new and.

improved Brick-Machine; land I do lhereby declare that the following is a full, clear, and .exact description thereof, which willenable'otbers skilled in theart to-make and use the same, reference being had to the accompanying drawings, forming .part ofl thisspecication, in which- Figure 1 represents a front view, partly in section, of my improved brick-machir.ie,` the plane'of section vbeing'indicated by the line :l: x, g.'3.

Figure 2.is a rearele'yation of 'the same.

This invention relates to a self-actingbrick-machine, which is so constructed that lthe clay'is placed into .the moulds, W-hich are formed in the circumfercnceof a 'revolving iv'heel, and is then pressed into'the required shape by means of plungers, which are also arranged ,in the rim of the said wheel, and which are forced against the clay into the moulds by an eccentric-cam o r crank, arranged on a vshaft in the wheel.

When pressed, the brick are ejected from the .moulds by the plungers, and lare thrown upon an endless apron, on which they are 'conveyed to the drying-room, or to any suitable place. The whole machineworks Aautomatically, all thatis necessary to start it being to place the clay into the moulds, and to revolve the horizontal driving-shaft."

A represents a wheel, 'which consists of a rim', A, spokes, b, and a hub, a, the spokes being arranged on the rear side of the wheel, and Whichis mounted on a horizontal shaft, B, that has its bearings in a frameC,

of suitable construction.- The riinA is made oi' Wood, or any other suitable' material. Itis perforated with,

radial oblongl holes c c, @f which two and two are arranged near each other, they being only separated by 'a thin partition, fl, as is clearly shown in' fig. 3,. and by dotted lines in g. 1. The outer circumference oi' the.

rim A is-la'ttenedabove each air of mouldsc c 'and round between eachsuch I air as isdclearl `shown in he.

. 1 p i y c `1. The width of the wheel A is, of course, in accordance with the length of brick to be used. Ou the shaft B is mounted a gear-wheel, e, as shown. D isa horizontal shaft, which has its bearings in the frame C, and which is arranged above the shaft B,Vas shown. Itis connected, by gear-wheels ff, withr the horizontal drivingshaft E,ivhich is provided with a ily-wheel, g, and which receives motion .by a belt passing over apulley, L, or

otherwise. lOn thevshaft D is mounted. a toothed segment, z', whioh meshes into' the gear-wheel e.l Thus, as

the driving-shz'ift revolves, the shaft D will be revolved, while the shaft B and its appendages receiveintermittent rotary motion by the toothed segment, the tv heel being turnedin the direction of .the arrow 1,.g. 1. E is a hopper or receptacle for the clay. It is arranged above the `vir-heel A on one side of the shafts B D,

and is open at the bottom, so that` the clay can be pressed by vany suitable mechanism `into that pair of moulds c c, which is under it. The bottom of each `mould isformed by aplirngelyj, which tits tight. in it, and which is provided with a stem, c, projecting toward thc shaft B, as is clearly shown in figs. 1 and 2. The plungers of those moulds 'which are under the hopper are drawn inn'. e., .they are as near to the inner circumference of the rim A as possible, as is indicated by dotted lines in tigY l. The moulds are, therefore, perfectly open to receive as much clay as they can hold.

When a pair 'of the moulds are thus iilled, the wheel Will be turned by 'the segment zi, and the Filled moulds will be carried so as to be vertically above the shafts B and D. Above the rim-of the wheel, vertically above the shaftB, is arranged n. boa-rd oi' plate, G, which is capable of covering pair o' moulds. 'it is pressed upon the hatt-cned. part of the rim by two eccentric-shafts H H, which are hung in the frame C above the board G, and of which one is operated by a connecting-rod, Z, which has a pin or roller at its lower end that ts into an eccentric-groove which is provided in the face ofa dish, I, mounted on the shaft D, as is indicated in ig. 3. Oscillating motion is thus imparted to the one shaft H, which thereby is made to alternately press upon the board and raise thesamathe latter being done by means of a hook, m, worlringnnder a pin, n, on the boards, as is clearly shown in iig. 2. @ne such hook Vshould b e mounted on either end ofthe shaft H, and a pin, u, be

provided on either end of the board G, so that yboth ends of the board are raised simultaneously. The shafts I I H H are connected by gear-wheel'ior'tcothed segments a o, iig. 2, so that they will move together. When the/ moulds are'uniler the board G, the same is pressed down by the eccentrica H, so as to completely close thel upper-entrancciof theumloulds, and tosustnin the upward pressure of the clay. The latter isthen pressed b v the plungersj into the required shape. The' plungers are movedup by asliding plate, p, which has a horizontal slot, through which a crank,.g, which isattached to the shaft'l), passes. During each revolution of the latter, the platep will therefore be once raised and lowered by the said crank'. The platep slides in a stationary frame, v, fixed in the wheel,- as `seen in iig. 2. The .upper edge oftheplate fits' under the lower end oftbc'stcms kk, and when raised by the crank, it raises the plungers in the moulds, and pressesthe clay. I l

While the brick are thus being pressed, itis necessaryzthat the wheelA should remain perfectly stationary, and altbough'it is not movedduring the said process by thetoothed segment, it may-'still bemoved a little by some -unforeseen causes, `whereby a great strain would be placed upon fthe wholemechanism. Toprevent any such shaking Aor other motion-during the process of pressing the brick, I have provided a spring-catch, r, which' fits into a notch, s, a series ofthe latter being provided inthe inner circumference of the rim A. The catchr is pressed into that notch s which is directly above the shaft B, by a spiral spring, as shown in iig. 1. l

As soon as the brick have been thus pressed in one pair of moulds, the spring-catchy' is moved out of its notch by a cam, t, on the shaft D, around which it ts, (see-fig. 1.) l The pressure of the eccentrics H upon the hoard G is released, and the latter raised 'by nieansot' the'hooks m, and the plate lo is lowered by the crank q, The wheel is .then turned by the segment so that the nentl pair of moulds'oomes under the board G. Those moulds which contain the ready-pressed brick are carried from under the hoard G, and the brick in them are' gradually pushed out the nearer they come' to be vertically under the shaft. This is done by a. stationary cam, J, which is arranged in the frame C, and underthe stems ic. vAs the .wheel isturned, the stems 7s are gradually Apushed out by this cam until, when the moulds are directly under zthe shaft B, the plungers will bey pushed out .asp far as possible,` and the brick ejected. They'fall upon van endlessiapron, K, shown fig. 1, and are thereby conveyed to any desired place. After the brick have been Ithus discharged, it is necessary that-the plungers should be .drawn in again to make room forv another charge of clay froml the hoppen For this purp'ose small pins or friction-rollers u u are secured to and project sidewise from the ends of 'the stems4 k'.

' L is a double or slotted stationarycamthrough'which the stems pass, and the inner edge of which forms a rest for the rollers uns the wheel is turned'. The form of this cam isisuch' that` the plnngers will be drawn in as soon as the moulds in which theyare arranged arrive under the hopper again, as is clearly shown in the drawings. .The' plungers, however, are -drawnin with diiliculty unless lubricated; Forthat purpose I provide 'a trough-,NQ below the wheelzA, containing oil, and in this I arrange a revolving brush, M, which takes upthe .oil fromthe trough, and applies it to the plungersbefore' they'are drawn back into the moulds by the action of the cam','as aforesaid. This shaft M, a.s well as that on which the apron is arranged, receives motion by means of belts, gear-wheels, Aor otherwise, from any one of the shafts arranged inor around` this machine.-

Having thus described my invention, what I claim as new, `and desire to secure by Letters Patent, is- 1. The board or plate G, in combinationl with the `eccentric-shafts H H, hooks m, and pins n, allmade and operating substantially as herein shown and described.

2. The' mould-wheellA, when provided with notches's s,'in combination with the spring-catch r and cam t, all made and operating substantially as and for the purpose herein shown and described.

3. The trough Nfas a receptacle for oil,and a brush, M, arranged to revolve the'rein, and contiguous with the plungers, to lubricate' them, -as speciied,'when .arranged beneath and operating in combination with the revolving mould-,wheel A, and secured to the base-plate @substantially as described and shown.

4. The combinations, with the wheel A, of the plate, G and eccentrics H, of the. plungers'j, stems k, and cam p, all made and operating as set forth. v
